To all whom "it may concern:

Be it known that I, Ancnsrn HYGONNET, citizen of France, residing at 31 Rue Pastourelle, Paris, in the Republic of France,

1 have invented new and useful Improvements gitudinal section of the razor fitted up ready for use. Fig. ,2 is an elevation at right angles to Fig. 1. Fig. 3 shows a plan view and a section of one part of the razor, 2'. e. the guard. Fig. 4 shows a plan and a section of another part of the razor, z". e. the backing plate. Fig. 5 is an elevation of the backing plate. Fig. 6 is a plan of the blade.

The razor comprises four parts: the handle a, the backing c, the blade 7' and the guard 72..

The cylindrical handle 8, which is in one piece, is perforated throughout its length and is screw-threaded internally at one end for engagement with the screw-threaded stem 6 in one with the backing c. The said backing is in the form of a rectangle the longer edges of which are slightly curved: its outer face is convexed and smooth for sliding over the skin and its inner or lower surface against which the blade bears is recessed at a so that the blade only bears on the periphery. Projecting from the under face of. the backing is a central stem b with a terminal screw-thread, and two small fins d are arranged one in the center of each of the short edges of the backing.

The blade f, shown in steel, whose two longer edges are curved and sharpened for formin the two cutting edges of the razor and w ose two shorter sides are straight and are each provided with a notch l in the middle so as to allow of lan in Fig. 6, is constituted by a small p ate of very thin curved sides cut to form teeth and its short straight sides are each provided at the middle with a notch 2 through which pass the fins d when the razor is fitted up. The upper face of the guard which bears against the blade when therazor is put together for use is recessed longitudinally at k so as only to contact with the blade on its longitudinal edges.

To put the parts together, the blade f is placed on the backing, being passed over the stem 6 and caused to engage the fins 0?; then the guard is placed above and also passed over the stem 1) and caused to engage the fins d. It only remains to screw the handle eon the stem 6. A razor thus constituted possesses a number of advantageous features.

The curved edges of the blade permit of shaving very close with the whole length of the blade without the necessity of applying the blade hard against the skin, as is necessary with blades with straight edges.

' The fins dwith the notches 1 and 2 avoid any possibility of any relative movementwof the parts, and assure parallelism between the edges of the blade and the toothed edges of the guard, and facilitate fitting up. Finally the recesses c .and k in the'backing and in the guard serve not only to lighten the razor, but assure a better grip of the curved cutting edges of the blade which is held between the edges of the said backing, and the guard, the central arts of these members not touching the bla c.

Having described my invention what I claim and desire to secure by Letters Patent of the United States is In a safety razor, the combination with a backing plate convexed on its outer side having two curved edges and a single longitudinal recess of substantial width travers ing its lower face and being provided with a depending threaded stem, and a depending guard having a notch to receive the dependname to this specification in the presence of ingllugi,1 of (iizhg kfitckrllg (plate, aid an intertwo subscribing Witnesses. nal t rea e an e esi e to en age the t hreaded stem of the ba ing plate and AUGUSTE HYGONNET' secure the parts in position, substantially as Witnesses: described. ANTOINE LAvors,

In testimony whereof I have signed my ELLWOOD AUSTIN WELDEN.
